ENERMAX LIQTECH TR4 AIO Liquid CPU Coolers Review

Enermax brings to us the first All-in-One coolers that are purpose-built for AMD's Ryzen Threadripper CPUs. We review both the Liqtech TR4 240 and the Liqtech TR4 360 using our overclocked 1950X Threadripper system and compare these to our XSPC RayStorm custom cooling loop. Yes, we are setting the bar high.

ENERMAX LIQTECH TR4 Assembly & Installation

Fan Assembly

On the assembly side of things, all the user needs to do is install the fans to his liking. Fan installation is the only true issue I had with the Liqtech hardware. I had issues getting the screws to thread into the mounting points on the radiator easily. When I say "easily," I actually mean it required a huge amount of force and pulling the fans sideways to get the holes to line up. Given that you have these vibrational dampeners on both the fans and the rails, it is a bit hard to see what the problem is. I think it is twofold. First, I do not think the holes for the screws in the radiator were well positioned. Second, I think the vibrational dampener is getting pushed into the mounting points as well making that issue worse. However, with a little elbow grease, a steady surface, and the proper size screwdriver it finally all did go together as you can see on the previous page. I hope that Enermax looks into this and addresses the issue, which of course should be simple to fix.

Enermax includes two pigtails for your fans and connecting those to the motherboard power, or directly to your PSU via a Molex connector. The daisy chain connector for the fans worked out well and is well constructed using wrap as well as shrinkwrap. The Molex adapter is sort of cheap in that it is simply a very fragile run of two-strand wire. Given these are PWM controlled fans, you will likely want to plug these fans into your motherboard anyway. We will touch more on that later in the review.

Retention Hardware

The bracket that locates and fixes the waterblock and pump combo down onto our Threadripper simply slides into a slot around the base of the block. There is a small detent pin that you will feel as you insert the bracket, simply push with a little force and it snaps into place. What is odd is that it only allows the bracket to slide on from one side. Remember that the Threadripper mounting points are asymmetric so you can only attach the bracket in one position. It seems like a better design decision would have been to make it slide on from either side giving the user the ability to mount the block with the tubing at the end of the socket desired.

The mounting system on the Liqtech pump/waterblock combination is simple, sturdy, and easy to work with. We have four hold-down posts that screw into the TR4 socket. These have large knurled knobs that allow you to do this by hand.

For actually mounting the block you will need a phillips head screwdriver to tighten down the spring assemblies. These will only screw down so far before running out of threads so it is "impossible" to overtighten the block hold-downs.

The Liqtech waterblock leaves plenty of room for populating all of the DIMM slots on our ASUS ROG Zenith Extreme motherboard. Our eagle-eyed readers will notice that the block is mounted with the protective plastic covering still on. Rest assured we did remove this for testing.

Radiator Mounting

As mentioned earlier, and worth mentioning again is that I highly suggest you mount the fans to the radiator before you install the radiator into your case (which you would likely do anyway). The tubing on the Liqtech is fairly forgiving and about 14 inches / 35.5 centimeters in length. But recall that our mounting hardware only allows us to mount the block with tubing at one end. That may, or may not, limit how much tubing length you have to work with.

Enermax Installation Video

Enermax has been kind enough to put together a video of the full installation procedure, and it is actually quite detailed and done very well.

The overall mounting procedure for the Liqtech could not be much simpler and you likely will not have to break out the instruction manual at all.
